The question is whether or not Nikon feels there is money to be made from re-releasing the FM-2n/FE2 which would be my best guess for the most achievable film camera. I doubt they'd be able to keep it at the old price point (about 370.00 1999 NY price).
How many would sell if they bundled the choice of body with some of the more recent discontinued Ai-S lenses; one package would be the 28mm f/2.8, the 50mm f/1.4 and the 105mm f/2.5 and be say 2,000.00? Would you bite at 1500.00? How about bundled for the 'Low Light Street Shooter Package' Black FM-2n 24mm f/2, 35mm f/1.4 and 50mm f/1.2 for 1800.00?
I would think that if they could keep the Body Only price to be under 1,000 they'd sell 25,000 units worldwide, in 2 years, probably fairly easily.
